The main difference between the oxygen pressure gauge and the ordinary pressure gauge is that the oxygen pressure gauge is an oil-free pressure gauge, that is to say, when the assembled pressure gauge is calibrated, the pressure is calibrated with gas or water, while the ordinary pressure gauge is calibrated with oil. Yes, because oxygen can’t ignite spontaneously, but it can burn all the forbidden oil.
structure:
The structure of the oxygen pressure gauge is basically the same as the general pressure gauge.High precision stainless steel Gauges socket
Character:
The oxygen meter measures oxygen, and the proportion in the air is indicated by numbers! ! !
The general pressure gauge measures the pressure, that is, the atmospheric pressure and the pressure in the pipeline (liquefied gas)! ! !
Difference: The oxygen gauge is marked 02, and the pressure gauge only has numbers! !
Switch direction:
The switching direction of the oxygen pressure gauge is different from that of the general pressure gauge. The oxygen pressure gauge is clockwise, and the combustible gas pressure gauge is counterclockwise, mainly to prevent misoperation
